Commitment beyond words
Comparing pointing and verbal reference in ambiguous contexts

Abstract
Commitment is pivotal in communication, as speakers are held accountable
for what they convey and may suffer reputational consequences after false statements.
While commitment has traditionally been associated with verbal assertions, everyday
communication often also involves gestures. We investigated whether commitment attribution
differs between purely verbal reference and reference established through the combination
of speech and pointing under conditions of referential ambiguity. In two experiments,
participants were asked to select objects to which an avatar was either pointing or
referring verbally. Across both experiments, pointing gestures elicited commitment-related judgements similar to verbal reference, regardless of the ambiguity or
correctness of gesture and speech. Furthermore, the results revealed that verbal reference
and pointing gestures triggered similar pragmatic inferences in partly ambiguous contexts.
These findings show that commitment may be attributed to speakers as much as to gesturers
and highlight the importance of integrating gestures into theories of commitment,
assertion, and pragmatic inference.
